Provides an introduction to simple machines.

"We don't think much about nails and screws, until we need to fix or build something. The screw is a fundamental tool in nearly all construction projects. While it may be small, it is a powerful invention that has changed the world forever. This accessible book introduces readers to this simple machine and its many uses through real-world examples. Detailed pictures with thorough annotations help readers understand key engineering concepts. Fascinating...

"Inclined planes are around us every day, though we may not always realize it. Wheelchair ramps, slides, and even stairs are all examples of inclined planes that are integral parts of daily life. Readers will learn all about this simple machine through interesting real-world examples. They'll explore detailed pictures of mechanical parts with extensive annotations and learn about key engineering principles. 'Technology in Action' spreads let readers...

"Have you ever wondered how seesaws go up and down or how screws stay secure in walls? In the How Do series, readers are welcome to guess along with the rest of us--and then explore the science behind the right answers. Beginning concepts of mechanical engineering including levers, wedges, inclined planes, and more are learned through diagrams, photos, and informative and engaging text"--Amazon.com.

Inclined plane may sound like a fancy word, but it's just a ramp! Learn how these simple machines make things easier.

"If you were designing a wheelbarrow, how would you make it move easily when you pushed it? How about wheels? In Wheels Make the World Go Round: Simple Machines for Kids, readers ages 5 to 8 learn how wheels work along with axles and how they use mechanical advantage to make it easier to move heavy objects from one place to another. Glossary, photos, and a hands-on activity make this book fundamental for STEAM learning."--

"How do you keep a door from closing? Try using a wedge! Wedges are one of the six simple machines that help make work easier by using mechanical advantage. In Wedges Make a Point: Simple Machines for Kids, readers ages 5 to 8 learn how a wedge's shape makes it perfect at stopping something heavy from moving, and separating material to split something--like banana bread--apart. Glossary, photos, and a hands-on activity make this book fundamental for...
